[GitBox <gi...@apache.org>]

juniskane opened a new pull request #525:
URL: https://github.com/apache/incubator-nuttx-apps/pull/525


   ## Summary
   Allow -4 and -6 command line options to select IPv4 or IPv6 on dual-stack devices, instead of always defaulting to IPv6
   Uses `getaddrinfo()` so can do host name lookups, option -n to disable (also works without CONFIG_LIBC_NETDB for IP addr only, like before)
   `getopt()` always called in a loop so no need for non-portable `optind = -1` construction
   Added missing `htons()` for port number
   
   ## Impact
   Command line syntax slightly changed, syntax `host:port` changed to have `port` as separate argument (easier for numeric IPv6)
   ## Testing
